A cable tension device

Abstract

The invention discloses a cable tension-resistant device, and relates to the field of tension-resistant devices. The cable tension-resistant device comprises a shell, a rotating shaft perpendicular tothe shell is inserted into one end of the shell, one end of the shell is provided with a cable outlet, the other end of the shell is provided with a first cable pass hole for enabling a cable to passthrough, a winding roller coaxial with the rotating shaft is fixedly connected to the rotating shaft, a first sliding block, a spring and a second sliding block are arranged in the shell along the axial direction, a second cable pass hole for enabling the cable to pass through is formed in the second sliding block, one end of the spring is fixedly connected with the first sliding block, the otherend of the spring is fixedly connected with the second sliding block, a stay wire is twined on the winding roller, a tangent point of the stay wire and the winding roller is located on an upper sideof the winding roller, the rotating shaft passes through an electric pole, a first nut is arranged on one side of the electric pole, a second nut is arranged on an opposite side of the electric pole,the first nut and the second nut both abut on the electric pole, the first nut and the second nut are both in threaded connection with the rotating shaft, and the second nut is located between the electric pole and the shell. The cable tension-resistant device disclosed by the invention has good durability.

Description

technical field [0001] The invention belongs to the field of electric power transmission, in particular to a cable tension device. Background technique [0002] The cable is fixed on the utility pole. After a period of time, the cable is easy to loosen, giving people a sense of insecurity visually; the cable tension device is used to prevent the cable from loosening and the cable from drooping; the existing technology uses springs for tension, After a long time of use, the elastic force of the spring is easily attenuated, resulting in a decrease in cable tension, which has the disadvantage of poor durability. [0003] Chinese patent authorization announcement number CN106448952B, authorized publication date 20170811, discloses a "Y-type strain insulator string and strain tower"; including: two strain strings, the first connection fittings, the first extension structure, and the second connection Fittings and the first triangular connecting plate, the shape of the first tria...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcoming of poor durability in the prior art, increase winding rollers and pull wires, and as the performance of the spring decreases, the shell rotates, and the pull wires elongate the spring to compensate for the attenuation of the spring performance, increasing the life of the present invention, and providing A cable tension device with good durability
